Products

• VMware Cloud Director

Issue/Introduction

• An attempt to download a vApp takes a substantial amount of time and then fails with an error similar to the following:
  
  A general system error occurred: Undeclared fault
 
Cause:
The object or item referred to could not be found.
  
  
• The NFC timeouts may have been increased, as detailed in the document below:
  
  Error: "com.vmware.ssdc.library.exceptions.VimTimedoutException: The VMware Cloud Director operation has timed out" when importing large OVFs
  
  
• Smaller downloads complete successfully.
• Shortly before the failure, in the ESXi vpxa logs, the NFC ticket is expired and revoked, as in the following example:

• There is then an attempt to renew the NFC ticket seen in the vpxa logs, but it fails since it can no longer be found:

Environment

VMware Cloud Director 10.6.x

Cause

If there is a delay in the process that renews the NFC ticket and the ticket expiration is set to a similar period as the renewal, the expiration can occur prior to the renewal and prevent the transfer from being completed.

Resolution

Review the NFC ticket timeouts, as detailed in the following article:

Error: "com.vmware.ssdc.library.exceptions.VimTimedoutException: The VMware Cloud Director operation has timed out" when importing large OVFs

Lower the config.httpNfcTicket.renewalPeriod value to a time that is less than the config.httpNfcTicket.timeoutPeriodMinute, as in the following example:

 

Name	Value
config.httpNfcTicket.renewalPeriod	6900
config.httpNfcTicket.timeoutPeriodMinute	120

 

Please note: These values are for illustrative purposes and may not be appropriate for your environment.
